Watch the Keep It Movin' online guitar lesson by Brooks Robertson from Fingerstyle Survival Guide
Keep It Movin' is a piece that roughly sticks to the simple progression of Em, F#min7b5 and B7. What's important is accurately and with good technique maintaining your thumb's alternating bass pattern. This will be a challenge to play the chords and melody simultaneously. Various inversions, bass muting, right and left hand dynamics and decorations will be combined into a musical idea you could hum.
